There is no direct relation between volts and BTU.
12,000 Btu is 4.7hp
18000 BTU means TON 1.5 ,12000 BTU means 1 TON
12000
12000BTU is 4.7hp
650 sft multiplied by 26 which means 16900. I BTU =12000 Divide 16900/12000 = 1.4 ton
12000 per hour
usually 20 btu's per square foot so......12000 btu's should do fine
12000 btu = 1 ton 1 ton per 400 sq ft 1200 / 400 = 3 3 times 12000 = 36000 btu
11800 BTU/hr is 3.46kW
12000 btu/min
12000 BTU is equivalent to approximately 3.51 kVA.
Btu and cubic meter are two different measuring units. Btu is the unit for heat transmission, like in ac units 12000 btu/hr. It means this ac unit would remove 12000 btu of heat from the room in one hour. where as cubic meter is the unit for volume.
